Kinetic watches are powered through the arm movement of the wearer. The difference to conventional mechanic watches, kinetic watches can run much more precise, thanks to the use of quartz technology. Because of a built in energy accumulator, kinetic watches can run up to 6 months without being moved or wound up. Some watches even have something called Auto Relay Technology and can save enough energy for up to 4 years of runtime! Whenever the watch is stationary it draws energy from the accumulator, but a small energy reserve is always kept so that if the watch should ever stop, just a few turns of the wrist will start it right up again (quick start function).
